摘　　要：由于传统配电网故障定位方法缺少对多个Agent之间的通信协调,导致定位精准度低、可靠性差等问题,为此研究并提出基于行波理论设计多电源配电网故障定位系统。采用.NET平台三层B/S结构体系设计故障行波定位信息处理子系统,通过数据处理模块处理获取数据信息,筛选多电源配电网故障信息,并在.NET平台上发布多电源配电网故障信息。当故障行波定位子系统发出调用数据命令时,故障行波定位信息处理子系统将故障信息传输到故障行波定位子系统中。通过多个Agent之间的通信协作调用故障数据,同时利用多端行波故障定位方法对故障数据进行定位,实现多电源配电网的故障定位。经过实验证明,与其他两种系统相比,所设计系统故障定位精准度在90%以上,系统故障定位精准度高。Due to the lack of communication and coordination between multiple agents in the traditional fault location method for distribution network,the positioning accuracy is low and the reliability is poor.To solve this problem,a fault location system for multi-power distribution network based on the travelling wave theory is designed in this paper.A three-layer B/S structure system on the.net platform is adopted to design a fault travelling wave positioning information processing subsystem.The data information is obtained through a data processing module,the fault information of multi-power distribution network is screened,and the fault information of multi-power distribution network is published on the.net platform.When the fault travelling wave positioning subsystem issues a call data command,the fault travelling wave positioning information processing subsystem will transmit the fault information to the fault travelling wave positioning subsystem.The fault data is invoked through the communication and coordination between multiple agents.Meanwhile,the fault data is located using the multi-terminal travelling wave fault location method,so as to realize the fault location of multi-power distribution network.Experimental results show that compared with two comparison systems,the designed system has a high fault location accuracy,which is more than 90%.
